Wow, thank you!!
 
I just might take you up on the offer of shoots next season.

 (I will have to look into how they are classified in MA) So, does it 
aggressively multiply/spread, or more like Lilacs, where if you keep around it mowed, it stays in check?  (i.e. rhizome spread, pea seed spread, or both, and lightly or aggressively?) 
I wouldn't say we are 'wet', but we are definitely not dry, and due to bedrock on this downslope of the mountain, water runs pretty close to the surface. (We literally have an underground stream under our foundation, and when the house was built (way before us & modern codes!), They ran a drainage line around house and right into the street sewer(water) collection system.  There is water constantly running into that...even when we were considered in a 'drought' this summer, there was still water running into the sewer drain constantly.
